The output pressure of the servo oil pump 2 is proportional to the mechanical lubricating oil pressure. When the system detects that the oil pressure output by the servo oil pump 2 is higher than the set pressure of the system, the PLC sends an instruction to the adjustable pressure reducing valve 12 according to the working pressure values of the pressure release valves of different models, and the adjustable pressure reducing valve 12 can be automatically opened to enable the output pressure to be stabilized at the preset pressure of the system.
